I may be out of the loop but I thought Halon was on the EPA's ****list..

From a cost-effectiveness standpoint, plain old dry chem ABC will work
fine for most of what you will come across. If you have anything that
involves magnesium, you might want a class D (metal) fire extinguishing
agent.

Dry chem can be corrosive if left sitting on a surface and it TASTES
like crap to get a mouthful of it (personal experience here) but if you
clean it off after things cool down, collateral damage in most
hydrocarbon fires can be minimized. If you have a fire in your radio
stack, the stack is likely toast anyways, but any use of Dry chem will
guarantee it.

I see a neighbor's hangar has two conventional fire extinguishers on
the wall. Not a bad idea, I'm sure. But for potential hangar fires are
halon still the best or are the conventional extinguishers just fine?
